The day job.
A decade in process engineering. The leverage that funds the curiosity.
Systems, opened up.
Interactive walkthroughs of the systems I touch in operations. Each one breaks down the process flow, performance KPIs, common failure modes, troubleshooting moves, and the global vendor ecosystem. Built as a reference for myself first; left public in case it's useful.
Cooling Water System
The unsung backbone of every plant.
Open-recirculating cooling. Tower, basin, pumps, exchangers, side-stream filtration, blowdown — and the chemistry that keeps them alive.
Demineralized Water System
Ultra-pure water, two ways.
Pre-treatment, bulk demin (IX or RO), polishing (mixed bed or EDI), storage. Same function, different technologies — the trade-offs that decide which path a plant picks.
Boiler Feed Water System
The water that makes steam.
Deaerator, BFW pumps, economiser, drum chemistry. Oxygen scavenging, phosphate / AVT regimes, and the failure modes that wreck a boiler from inside.
COGEN
Power and steam, one fuel.
Gas turbine, HRSG, steam turbine, condenser. Heat-rate accounting, supplementary firing logic, and where the cogen profit really comes from.
Raw Water Treatment
Where the water story starts.
Intake, screening, coagulation, flocculation, clarification, filtration. Source-water variability and how upstream decisions cascade into every downstream system.
